We moved into this house two and a half months ago and this pool is about to put me over the edge. I found this site after two weeks of daily visits to the pool store and that not helping at all. I did manage to get the pool pretty clear with everything I learned here after a couple weeks of doing things myself. About a month ago this "stuff" showed up and I can't get rid of it. It's not really in the water, the water is clear, but it is on the sides and bottom of the pool. I have been vacuuming every few days since like I said it's actually on the bottom of the pool and not in the water. I do end up stirring it up a bit though and the water gets green but I just wait a few days again for it to sink.
Here you can see that the shallow end isn't too bad but the deep end is green
A lot always settles on the slope going into the deep end.
I just tested the water too and this is what I got with my Taylor k-2006
